MOTOR.

SPECIFICATION forming part of Letters Patent No. 431,56'7, dated July 8, 1890.

Application filed April 20, 1889. $erial No. 307,937. (No-model.)

To all whom it may concern.-

Be it known that 1, JAMES B. ERWIN, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and 5 useful Improvements in Motors; and I do hereby declare thefollowing to be a full, clear, and exactdescription of said invention, reference being had to the accompanying drawing,'and to the letters of reference marked Io thereon, which form a part of this specification.

The object of my invention is to provide an engine through which the expansive force of steam may be converted into high-speed rotary motion by the direct action of the forces employed and the use of a crank, pitman,

cross-head, and the usual mechanism essential to the construction of the ordinary reciprocating engine thereby dispensed with.

My invention relates to improvements in a certain engine for which Letters Patent of the United States No. 384,612 were granted to me June 19, 1888, in and by which, as in the present case, the expansive power of steam is con- 2 5 vented into high-speed rotaryrnotion through water or other liquid acting upon a turbine water wheel. scribed in said patent, two water-receivers are employed, and the same water is driven by 0 the direct action ofv the steam on the water repeatedly over and over again from one of said receivers to the other. By my'improvements the same water is forced by contact with one side of the steam-actuated piston 3 5 from one end of the cylinder to the other upon the opposite side of said piston, and in its course such water is driven with great force, as" stated, upon a turbine water-wheel, whereby such wheel is driven with high speed,

2* adapted to running dynamos, circular saws,

and other high-speed machinery direct without the use of intermediate machinery.

The construction of my invention is explained by reference to the accompanying 5 drawing, which represents a side view thereof.

As a device for thus forcingthe same water continuously in the same direction upon a motor-wheel, I employa steam-actuated forcepump or hydraulic compressor of the ordinary construction, consisting of a substantial frame A, steam-cylinder B, steam-chamber 0, provided with ordinary steam controlling By my previous engine, de-

valves, water-cylinder D, preferably of less diameter than the steam-cylinder B, waterchamber E, provided with ordinary watercontrolling valves, piston-rod F, connecting together the pistons of the respective cylinders B and O, and air-chamber G, all of which parts are constructed and arranged relatively to each other in the ordinary manner.

H is the inlet-water duct to the water-cylinder, through which water is led alternately upon the respective sides of the piston therein as said piston reciprocates from one end of the cylinder to the other.

I is the outlet-water duct, through which the water is forced in a continuous stream from said chamber E upon the water-wheel.

J is an impact water-wheel of ordinary construction, which is inclosed and supported in place by the case or frame K. The discharge end of the outlet-duct I is connected with the wheel-case K in such a manner that the wa ter as it is discharged therefrom is brought with great force upon the mot0r-wheel,whereby said wheel is caused-t0 rotate with great :speed with and upon its supportin -shaft L.

The inlet end of the inlet-Water duct- H is connected to or communicates with the Wheelcase K, whereby as the water escapes from said wheel it-is led back and returned to said Water-cylinder upon the opposite side of the piston, from which it escapes. vious that the same water is caused to flow continuously over and over again upon said Thus it is ob-- motor-wheel, as mentioned, with each reciprocating movement of the piston.

It is obvious that. oil or other liquid may, if desired, be substituted for the water used upon the Wheel, and also that any desired form of motor-wheel may be used.

The relative size of the discharge nozzle or duct to that of the water-cylinder is such that the water-piston acts with a slow easy movement, making only about one to two strokes per second, while the water-wheel, which is actuated by the water thus discharged upon it, rotates at the rate ofabout two thousand times per minute. Thus it isobvious that with a comparatively slow and easy movement of the wearing parts of the machine I am enabled to produce a rapid movement of the motor-wheel, and as the motor-wheel rotates with its shaft free from contact with its inclosing-case and is actuated by a liquid with but slight friction the durability of the engine is necessarily very great compared the respective sides of the piston in said was ter-cylinder, all substantially as and for the purpose specified.

2. In a high-speed engine, the combination, in a single machine, of a steam-actuated reciprocatin g force-pump, consistingof frame A, steam-cylinder B, water-cylinder D, said cylinders B and D being each provided with ordinary reciprocating pistons and provided, respectively, with steam and Water controlling valves, piston-rod F, communicating between the pistons of said steam and water cylinders, Water-Wheel J, Wheel-supporting shaft L, Wheel-inclosing case K, water-chamber E, discharge duct-or nozzle I, communicatin g from said Water-chamber E to said water-Wheel Within said wheel-inclosing case, and return or inlet duct II, communicating from said wheel-inclosing case back to said Water-cylinder, said Wheel J being adapted to be rotated upon its supporting-shaft free from contact with its inclosing-case by the impact of Water from said discharge nozzle or duct, substantially as and for the purpose specified.

In testimony whereof Iaffix mysignature in presence of two Witnesses.

JAMES B. ERWVIN.
